Fire Weather Planning Forecast for the Florida Keys
National Weather Service Key West FL
423 AM EDT Tue Aug 19 2025

.Discussion...
Relatively light and variable winds will assume a northerly to
northwesterly component this morning. As Major Hurricane Erin
makes a north turn today, and remains well to the east of our
area, we aren`t expecting significant, direct impacts. However,
rain and thunderstorms chances will tick up just a little bit by
tomorrow. Looking ahead, drier and lighter winds will return by
Thursday. Fire weather concerns are at a minimum right now due to
relative humidity values above 60%.
